1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 04AUG26 1800Z, TROPICAL DEPRESSION 13W (KUJIRA) WAS 
LOCATED NEAR 17.5N 118.9E, APPROXIMATELY 212 NM NORTHWEST OF MANILA, 
PHILIPPINES, AND HAD TRACKED NORTH- NORTHWESTWARD AT 02 KNOTS OVER 
THE PAST SIX HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 
30 KNOTS GUSTING TO 40 KNOTS. SEE REF A (WTPN32 PGTW 042100) FOR 
FURTHER DETAILS.
      (2) AT 04AUG26 1800Z, TYPHOON 12W (DOLPHIN) WAS LOCATED NEAR 
25.3N 139.3E, APPROXIMATELY 625 NM EAST OF KADENA AB, AND HAD TRACKED 
WESTWARD AT 12 KNOTS OVER THE PAST SIX HOURS. MAXIMUM SUSTAINED 
SURFACE WINDS WERE ESTIMATED AT 105 KNOTS GUSTING TO 130 KNOTS. SEE 
REF B (WTPN31 PGTW 042100) FOR FURTHER DETAILS.
      (3) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 94W) PREVIOUSLY LOCATED NEAR 
17.1N 166.1E IS NOW THE SUBJECT OF A TROPICAL CYCLONE WARNING. SEE 
PARA. 1.A.(1) FOR FURTHER DETAILS.
      (2) AN AREA OF CONVECTION (INVEST 96W) HAS PERSISTED NEAR 17.1N 
166.1E, APPROXIMATELY 134 NM SOUTH-SOUTHWEST OF WAKE ISLAND. ENHANCED 
INFRARED IMAGERY (EIR) DEPICTS A BROAD AND VERY ELONGATED REGION OF 
TROUGHING WITH DEVELOPING LOW-LEVEL CIRCULATIONS (LLC) POSITIONED IN 
THE WESTERN END OF THE TROUGH AND IN THE NORTHEASTERN PORTION, IN THE 
VICINITY OF WAKE ISLAND. A PARTIAL 040952Z ASCAT-B PASS SHOWED SHARP 
CYCLONIC TURNING TO THE SOUTH OF WAKE ISLAND BUT DID CAPTURE THE 
ENTIRE EXTENT OF THE BROAD ROTATION. ENVIRONMENTAL ANALYSIS REVEALS 
FAVORABLE CONDITIONS ARE SUPPORTIVE OF DEVELOPMENT WITH LOW VERTICAL 
WIND SHEAR (10-15KTS), WARM SEA SURFACE TEMPERATURES (29 TO 30 C), 
AND GOOD POLEWARD OUTFLOW. HOWEVER, THE WINDOW OF OPPORTUNITY FOR TC 
DEVELOPMENT IS SMALL, AS GLOBAL MODELS DEPICT THE CIRCULATION MOVING 
UNDER AN UPPER-LEVEL TROUGH AND INTO A DRIER ENVIRONMENT, WHICH WILL 
SUPPORT THE TRANSITION OF THE SYSTEM INTO A SUBTROPICAL CYCLONE AFTER 
ABOUT 36 HOURS. GLOBAL MODELS INDICATE THE STEADY DEVELOPMENT OF 96W 
INTO A BROAD, BRIEFLY TROPICAL CYCLONE WITHIN THE NEXT 24 TO 36 
HOURS. ENSEMBLE MODELS ALSO AGREE IN THE CONTINUED DEVELOPMENT OF 96W 
AND FOR IT TO TAKE A GENERAL NORTHWARD TRACK OVER THE NEXT 48 HOURS. 
MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 17 TO 22 KNOTS. 
MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1001 MB. THE 
POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE 
WITHIN THE NEXT 24 HOURS REMAINS LOW.
      (3) NO OTHER SUSPECT AREAS.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.
2. SOUTH PACIFIC AREA (WEST COAST OF SOUTH AMERICA TO 135 EAST):
   A. TROPICAL CYCLONE SUMMARY: NONE.
   B. TROPICAL DISTURBANCE SUMMARY: NONE.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.
3. JUSTIFICATION FOR REISSUE: UPGRADED AREA IN PARA 1.B.(1) TO 
WARNING STATUS//
